1. James Watt patents his improved steam engine 1769

   Watt also coined 'horsepower' as a marketing tool — comparing his engines to the draft horses customers would be replacing. The watt unit is named for him.

2. Abraham Lincoln is shot at Ford's Theatre 1865

   General Grant declined an invitation to join Lincoln in the box that night. Booth, a famous actor, knew the play well enough to time his shot to a big laugh line.

3. Disneyland opens its gates in Anaheim, California 1955

   Opening day was a fiasco insiders called 'Black Sunday': heat melted the fresh asphalt, fountains failed, and thousands entered with counterfeit tickets.

4. Humans walk on the Moon for the first time 1969

   The Apollo guidance computer had less processing power than a modern pocket calculator — and alarms from it nearly aborted the landing.

5. The Sydney Opera House officially opens 1973

   It opened ten years late and roughly fourteen times over budget. Architect Jorn Utzon resigned mid-project and never returned to see it finished.

6. Nations adopt the Paris Agreement on climate change 2015
